Objective To analysis the changes of serum adiponectin level in patients with breast cancer and its clinical signifi‐cance .Methods 35 cases of serum adiponectin levels in breast cancer patients using enzyme‐linked immunosorbent assay ,and 35 healthy serum adiponectin level in peripheral blood of women ,analysis of significance of changes of serum adiponectin levels in breast cancer patients .Results Average serum adiponectin level in patients with breast cancer group(6 .13 ± 1 .55)μg/mL ,health group average serum adiponectin levels (8 .72 ± 1 .86)μg/mL ,the difference was statistically significant(P<0 .05) .Postmenopausal women in breast cancer group and health group compared with premenopausal women ,the serum adiponectin levels were signifi‐cantly increased ,there was a statistically significant difference(P<0 .05) .Lymph node metastasis of breast cancer serum adiponec‐tin levels were significantly lower in patients without lymph node metastasis in patients with breast cancer ,the difference was statis‐tically significant(P<0 .05) .Serum adiponectin level in breast cancer patients with stage Ⅱ and Ⅲ were significantly lower than breast cancer patients with stage Ⅰ ,there was a statistically significant difference(P<0 .05) .Conclusion Serum adiponectin levels as an important marker in the diagnosis of breast cancer ,serum adiponectin level and grade of the tumor ,lymph node metastases . Significantly reduced serum adiponectin level in patients with breast cancer ,and not under the influence of patients with menopause .

Objective:To establish the model of rats with UC by 2,4,6 trinitrobenzene sulfonic acid ( TNBS)/ethanol to understand the changes of IL-17,IL-23,TGF-β1,IFN-γin pathogenesis of ulcerative colitis (UC) and the impacts of mesalazine,mont-morillonite powder and clostridium on that.Methods:85 rats were divided randomly into 6 groups including the model ,mesalazine, montmorillonite,clostridium,mesalazine combined with montmorillonite powder group (15 rats per group ) and an additional control group of 10 normal rats.TNBS/ethanol was used to establish the model of rats with UC.The dosage of model, mesalazine, montmorillonite powder ,clostridium and mesalazine combined with montmorillonite powder were converted by surface area of rat and given to the rats by gastric-tube daily.All rats were executed at the 12th day of the molding and treatment ,and the blood and colon samples were collected.The content of IL-17,IL-23,TGF-β1,IFN-γwas measured in the blood by the ELISA method.The different changes of the four cytokines were compared separately.Results: ( 1 ) TNBS/ethanol was used to establish the model of rats with UC.The obvious inflammation can be observed on distal colon of rats by pathologic sections of HE stained .(2) The levels of plasma IL-17,IL-23 and IFN-γin the model,mesalazine,montmorillonite,clostridium and mesalazine combined with montmorillonite powder group were higher than ones in the control gruop (P<0.05),meanwhile,the levels of plasma TGF-β1 are lower (P<0.05).3.Comparing with the model group,the levels of plasma IL-17,IL-23 and IFN-γin the mesalazine,montmorillonite,clostridium and mesalazine combined with montmorillonite powder group were lower , and the levels of TGF-β1 were higer.The differences have statistic significative ( P<0.05).(4)Comparing the efficacy of treatment among mesalazine ,montmorillonite powder,clostridium and mesalazine combined with montmorillonite powder ,mesalazine and mesalazine combined with montmorillonite powder gets the best results ( P<0.05 ).The efficacy between montmorillonite powder and clostridium is similar.Conclusion:(1) TNBS/ethanol can be used to establish the model of rats with UC and can be successfully approved by the measurement of symptoms and pathologic investigation .(2)The IL-17,IL-23 and IFN-γare very active higher in the blood of rats with experimental ulcerative colitis induced by TNBS /ethanol, and have a positive correlation with inflammation.The TGF-β1 is in decrease in the blood of rats with colitis , and has a Negative Correlation with inflammation.(3)Mesalazine,montmorillonite powder,clostridium and mesalazine combined with montmorillonite powder may renovate the damage of inflammatory tissues of rats with experimental ulcerative colitis , and relieve the symptom of inflammation by reducing exudation of proinflammatory cytokines IL-17, IL-23 and immune regulatory cytokines IFN-γby producing the exudation of proinflammatory cytokines TGF-β1 to be good for recovery of UC.
